Hame-tug fastener



irn STATES SYLVESTER B. DAVIS, OF STOCKTON, CALIFORNIA.

HAM E-TUG FASTENER.

SPECIFICATION forming part of Letters Patent N o. 611,427, dated September 27,1898. Application filed December 9, 1897. Serial No; 661,211. (No model.)

T0 all whom it may concern:

Be it known that I, SYLvEsTER B. DAvIs, a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in llame-Tug Fastenings; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the figures of reference marked thereon, which form a part of this specification.

My invention relates to that class of hametug fastenings which are so constructed as to permit of the trace or tug being readily lengthened or shortened; and it consists in the peculiar construction, novel combination, and adaptation of parts hereinafter described, and particularly pointed out in the claim hereunto annexed, reference being had to the accompanying drawings for a more complete understanding thereof, in which- Figure lis a side elevation of my improved hame-'tug fastening with a part broken away, showing the inner parts. Fig. 2 is a top View of the same. Fig. 3 is a detail face view of the end of the tug with its attendant fastening. Fig. 4 is a side view of the same. Fig. 5 is a sectional view through line X X, Fig. l.

Similar figures of reference indicate corresponding parts in the several views.

The hame 1, which is of ordinary pattern, has the usual staple 2 rigidly inserted at a suitable point therein. A strap 3, preferably of leather, is rigidly attached in any suitable manner; but I prefer riveting the same to the back of a long loop or sheath 4c, which is preferably composed of sheet metal fashioned to the desired shape, as shown in Fig. 5. The strap 3 has one end extending beyond the loop 4L, which said end is doubled around the staple 2 and passed beneath the end of the loop 4: and rigidly attached thereunder by a rivet 5. The loop or sheath 4 has oblong openings G at suitable intervals in either side of the same, such openings being arranged abreast in pairs for the purpose, as will be shown.

In the forward end of the trace or tug 7 an automatic catch is attached, which is composed, essentially, of a casing 8, formed by a piece of sheet metal, doubled,as shown at 9, Fig. 4t, a V- shaped spring 10, which is inserted between the partsof the casing 8 and attached therein, with its free ends extending rearwardly, by means of a pin or rivet 11, and two hooks orcatches 12, arranged one on either .side of the spring 10 and pivotally attached to the said casing 8 by means of rivets,sucl1 hooks 12 being so designed as to be engaged by the said spring 10, which maintains such hooks in an extended position, there being a shoulder 13 on each of the same therefor. 'IAhe shank of each hook 12 is adapted to rest within the casing 8 and the hook only to protrude beyond the sides of the casing for the purpose of engaging with the sides of the openings G, as hereinafter set forth.

One strip of the leather of the trace 7 is doubled over the end of the casing 8 and rests at opposite sides of the same, thereby completely covering the casing 3 in the front and rear sides, and another strip of leather may be inserted between the loose ends of the casing 8 a suitable distance therein and maintained in such position by means ofrivets 15.

The construction of trace described, while very neat in appearance, is strong and durable and is further advantageous, since its rounded end, formed by doubling the metallic strip 9 and the outer leather strip, may be readily introduced into the sheath'll. The doubling of the outer leather strip over the doubled metallic piece 8 is also advantageous, because it obviates the liability of a casual disconnection of the trace in the event of the rivets giving away.

The mode of operating my improved hametug fastening is as follows: The hooks 12 are pressed inwardly by the thumb and finger of the operator, and the end of the trace 7, having the casing 3 attached thereto, is inserted in the loop or sheath 4t until the hooks i12 engage' with the openings 6, whereupon such hooks 12 are pressed in engagement with the sides of such openings 6 by means of the spring l0. The hooks 12 may be pressed in engagement with any of the openings@ that will bring the trace to the required length by repeating the operation vabove described.

The applicability of the metallic loop or sheath 4t is apparent in view of its stability, which prevents the crushing of its sides and IOO thus impeding the ingress and egress of the end of the trace 7 in and from the said loop or sheath 4. p

Having described my invention, what I olairn is- In the hame-tug fastening, the combination of a hame, a metallie loop or sheath connected With the hame and Ahaving pairs of alined openings in its opposite Walls at intervals in its length, and the trace comprising the U- shaped piece of metal 8, the outer, doubled strip of leathercovering the U-shaped piece of metal, the inner leather strip with one end interposed between the parallel arms of` the piece of metal 8, Catches pivotally mounted between the parallel arms of the piece of metal SYLVESTER B.
